Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02815 |
| Opus 5 | $0.00000 | $0.01407 |
| Sonnet 5 | $0.00000 | $0.00563 |
| Haiku 4.5 | $0.00000 | $0.00281 |
Grade A, and why
hardware-specs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ESP32-S3-CAM-GC2145 Hardware Specs (authoritative)
Read this before writing any code that touches peripherals, memory, Wi-Fi, camera, or audio. All GPIO and address numbers below are verified against the vendor BSP (ref/demo/ESP32-S3-CAM-OVxxxx/examples/ESP-IDF-v5.5.1/04_dvp_camera_display/components/waveshare__esp32_s3_cam_ovxxxx/include/bsp/esp32_s3_cam_ovxxxx.h) and this unit's boot logs.
Chip
- ESP32-S3 Xtensa LX7, dual-core @ 240 MHz — confirmed
cpu_freq: 240000000 Hz - Chip rev v0.2, efuse block rev v1.3, QFN56
- FPU (single-precision), SIMD (PIE vector), WiFi 4 + BLE 5. No 802.15.4
- Dual-core →
xTaskCreatePinnedToCore()is valid; pin Wi-Fi to 0, app to 1 for jitter isolation
Memory
- SRAM: 512 KB on-chip. After boot: ~316 KiB main + ~21 KiB + ~7 KiB RTCRAM available for dynamic alloc
- PSRAM: 8 MB OPI (AP Memory gen-3, 64 Mbit density, 80 MHz, hybrid-wrap 32-byte burst, latency 10 cycles)
- Boot log:
Adding pool of 7488K of PSRAM memory to heap allocator(+33 K gap) ≈ 7.5 MB free to heap
- Boot log:
- Flash: 16 MB external NOR, QIO @ 80 MHz, 3.3 V
- Wi-Fi/LWIP prefer SPIRAM (
WiFi/LWIP prefer SPIRAMin boot log) - Full 320×240 RGB565 fits trivially; full 1600×1200 UXGA raw (3.84 MB) fits in PSRAM
I²C Bus (single shared bus)
SCL = GPIO 7, SDA = GPIO 8, 100 kHz (camera example) / 400 kHz (audio example).
| Device | I²C address | Role |
|---|---|---|
| ES8311 | ES8311_CODEC_DEFAULT_ADDR (0x18 7-bit / 0x30 8-bit) |
Audio codec control (playback path) |
| ES7210 | ES7210_CODEC_DEFAULT_ADDR (0x40 7-bit typical) |
4-ch ADC control (mic array) |
| GC2145 (SCCB) | 0x3C 7-bit | Camera sensor control |
| CH32V003 IO Expander | CUSTOM_IO_EXPANDER_I2C_CH32V003_ADDRESS |
LCD reset/backlight, touch reset, battery ADC, red LED |
| LCD Touch controller (if LCD fitted) | 0x15 (CST816S/CST328) or 0x38 (FT6336) | Depends on LCD variant |
The esp_codec_dev library uses the 8-bit convention (0x30 for ES8311); driver internally does addr >> 1.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hardware-specs is a command published in the GitHub repository chayuto/ws-ESP32-S3-CAM (5 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,815 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
